Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607970, here are decompositions:

61 + 31607909 = 31607970
67 + 31607903 = 31607970
73 + 31607897 = 31607970
101 + 31607869 = 31607970
103 + 31607867 = 31607970
113 + 31607857 = 31607970
131 + 31607839 = 31607970
139 + 31607831 = 31607970

Showing the first eight; more decompositions exist.
